Dear List, I have examined the sp, maptools, and shapefiles packages (Windows) but cannot seem to figure out a solution for writing shapefiles for 'curvy shapes'. The scenario is that I generate a series of polygons, circles, and ellipses on a plot and would like to convert them to shapefiles. Since the circles and ellipses are do not return a coordinate list during the plotting

Dear List, Running on a PC (Windows 2000) with 256 MB RAM, Version R1.9.1 I have a relatively simple problem, which I can solve for relatively small datasets, but run into difficulties with larger ones. I believe that my approach is a hack rather than something elegant and I was hoping that somebody on this list might help me improve my code. Basically, given a vector of values (e.g.,

Hello list members, I am working with simulated data for landscape pattern analysis. I have 1000 replicates of binary (2 colour) gridded landscapes at each combination of 9 levels of class proportion and 11 levels of spatial autocorrelation. The results are stored in an array as follows: > dim(surfaces) [1] 38 9 11 1000 The dimensions are defined as follows: [x,,,] 1:38, integers

Dear list, I have a dataset as follow and I would like to count the frequencies for the combination of the two variables (f1 and f2) for each id. I know it is should be straight forward, but I just don't know how to do it in R. Here is the SAS code I will use to get the output I want : proc means nway; class id f1 f2; var flag output out=temp; Dataset: id f1 f2 flag 798 1 2

Dear all, I have a data frame that looks like this: c1 c2 c3 A B C B C A A A B and so on; I?d like to produce one single vector consisting of the columns c1,c2, c3, such that vector=("A","B","A","B","C","A","C","A","B") I guess it?s easy to do but I don?t know how...Can anyone

hi there, trying to follow the steps of Yan & Rossini 2003, I have two problems : first when I 'make CrossCompileBuild', I get : ****************************************************************************** make[1]: Entering directory `/home/ros/RWORK/CROSSSOMP/WinR/R-1.8.0/src/gnuwin32' make -f Makefile.docfiles make[2]: Entering directory

Hello, I am a newbie. I can run the following code stored in "test.txt" without error using my XP machine: x <- scan("C:\\Rwork\\A.txt") x10 = filter(x, rep(1/10,10), sides=1) x x10 for(i in 10:length(x)){ if (x[i] > x10[i]) diff[i]="b" else diff[i]="s" } However, if I run it in another PC that uses Windows 7, the following error occurs:

This is a multipart message in MIME format. --=_alternative 00812CFCCA256D66_= Content-Type: text/plain; charset="us-ascii" Two points in respect to PR#2867. First, the trivial one: (1) In Lapack.c, on lines 806 and 812, there are calls of F77_CALL(dgeqp3). But the error messages on lines on lines 809 and 815 refer to "dqeqp3", i.e., they currently have a "q"

Dear all, i was working under R 1.6.2 but i wanted to install bioconductor under WinXP, and because R 1.7.1 contains the TclTk package and automatic installation of bioconductor packages, so i install it. Everything is fine except this message which appear after the installation of packages. "> local({a<- CRAN.packages(CRAN=getOption("BIOC")) +

All, I've encountered the same problem as others who have posted under the same subject. I've had R-1.8.1 installed and running since it was released. Yesterday morning when I tried to start Rgui.exe I got the subject error message. Since I live at the whim of the network administrators I can only assume it was a recent MS critical update. I tried installing R-1.9.0 but no joy. I

** High Priority ** I have been trying to read an SPSS file into R using read.spss ("C:/Documents and Settings/Roderick Harrison/My Documents/RWORK/ihisdat.sav", use.value.labels = TRUE, to.data.frame = FALSE, max.value.labels = 500, trim.factor.names = FALSE, trim_values = TRUE, reencode = NA, use.missings = to.data.frame) Each time (at least 5 or 6 by now) I get the following

Dear WizaRds, I wrote a small function in R and would like to create a package. The necessary documentation is done, Rtools etc. are installed and I am still unable to complete the process under Windows. I did extensive research in the archives and read the Murdoch-Sutherland website on the Rtools and MikTeX hints. I realize that I understand only half or less of what is said there

Hi, I recently discovered the R program and I thought it could be useful to me. I have to analyse data saved as .Px file (x between 0 and 8 - .P0 files have 18 lines at the beginning that I have to skip). New files are generated everyday. This is my strategy : In order to analyse the data, I first want to copy the new data in a database in MySQL (which already contains the previous data). So

Hi, I am trying to run the "schools" example in the rbugs library (running winbugs in linux via wine-20041201) but keep getting the following error. Note I have tested wine and winbugs to confirm that both are operational. Error in runBugs(bugs, script.file, n.chains, workingDir, useWine, wine, : BUGS stopped before getting to coda. The command I'm using is:

R2WinBUGS users, I'm getting the error message "monitor could not be set" when I try to monitor (and output to R) a response variable that includes missing data (NAs)...ie.e imputing for y. Setting monitors for other parameters works OK and running the R-generated WinBUGS script file in WinBUGS, also works OK. Below is my R code and the log.txt file output by R2WinBUGS. As I want to

Hello folks, I am having a problem installing pbatR package. (My R version is 2.8.1.) As I execute a command > install.packages(lib='/usr/local/apps/R-2.8.1/lib64/R/library', "pbatR") it detects lack of rootSolve package and attempts to install it. But cannot seem to compile it, and the rest is aborted. Any hint as to what I can do? Thank you in advance for your

By default, Rails logs all parameters passed to a controller method. As far as I can tell, this happens in both development and production modes. I have a form that collects some sensitive data. I don''t want that data sent to the log, at least not in production mode. Of course, I''d still like to log everything else. Is there a way to accomplish this? -- Posted via

I was trying to deal with foreign key issues related to order of fixture loading when I came across this: http://techpolesen.blogspot.com/2007/04/rails-fixture-tips.html This got me looking deeper into rails and I noticed that db:fixtures:load calls Fixtures.create_fixtures once for each fixture file. However, Fixtures.create_fixtures is capable of taking multiple files and also handle the

HI All R Gurus, Please reply directly to this email if you have a suggestion, as I am not currently an R-help member. I would like to complete a non-linear regression with groups. Having gone down the path of completing such things under GENSTAT, I would prefer to do it with R. My example data set is... TimeTreat ExtrVol2 SorbedT ET1 39.5 384.5 ET1
